Benchmark with fio |

:::tip
Trash is enabled in JuiceFS v1.0+ by default. As a result, temporary files are created and deleted in the file system during the benchmark, and these files will be eventually dumped into a directory named .trash. To avoid storage space being occupied by .trash, you can run command juicefs config META-URL --trash-days 0 to disable Trash before benchmark. See trash for details.
:::
Perform a sequential read/write benchmark on JuiceFS, EFS and S3FS with fio.
The following tests are performed with fio 3.1.
Sequential read test (numjobs: 1):
fio --name=sequential-read --directory=/s3fs --rw=read --refill_buffers --bs=4M --size=4G
fio --name=sequential-read --directory=/efs --rw=read --refill_buffers --bs=4M --size=4G
fio --name=sequential-read --directory=/jfs --rw=read --refill_buffers --bs=4M --size=4G
Sequential write test (numjobs: 1):
fio --name=sequential-write --directory=/s3fs --rw=write --refill_buffers --bs=4M --size=4G --end_fsync=1
fio --name=sequential-write --directory=/efs --rw=write --refill_buffers --bs=4M --size=4G --end_fsync=1
fio --name=sequential-write --directory=/jfs --rw=write --refill_buffers --bs=4M --size=4G --end_fsync=1
Sequential read test (numjobs: 16):
fio --name=big-file-multi-read --directory=/s3fs --rw=read --refill_buffers --bs=4M --size=4G --numjobs=16
fio --name=big-file-multi-read --directory=/efs --rw=read --refill_buffers --bs=4M --size=4G --numjobs=16
fio --name=big-file-multi-read --directory=/jfs --rw=read --refill_buffers --bs=4M --size=4G --numjobs=16
Sequential write test (numjobs: 16):
fio --name=big-file-multi-write --directory=/s3fs --rw=write --refill_buffers --bs=4M --size=4G --numjobs=16 --end_fsync=1
fio --name=big-file-multi-write --directory=/efs --rw=write --refill_buffers --bs=4M --size=4G --numjobs=16 --end_fsync=1
fio --name=big-file-multi-write --directory=/jfs --rw=write --refill_buffers --bs=4M --size=4G --numjobs=16 --end_fsync=1
All the following tests are all performed using fio on a c5d.18xlarge EC2 instance (72 CPU, 144G RAM) with Ubuntu 18.04 LTS (Kernel 5.4.0) operating system. JuiceFS uses a local Redis instance (version 4.0.9) to store metadata.
JuiceFS mount command:
./juicefs format --storage=s3 --bucket=https://<BUCKET>.s3.<REGION>.amazonaws.com localhost benchmark
./juicefs mount --max-uploads=150 --io-retries=20 localhost /jfs
EFS mount command (the same as the configuration page):
mount -t nfs -o nfsvers=4.1,rsize=1048576,wsize=1048576,hard,timeo=600,retrans=2,noresvport, <EFS-ID>.efs.<REGION>.amazonaws.com:/ /efs
S3FS (version 1.82) mount command:
s3fs <BUCKET>:/s3fs /s3fs -o host=https://s3.<REGION>.amazonaws.com,endpoint=<REGION>,passwd_file=${HOME}/.passwd-s3fs
